javascript - fire external script background with js? -


is possible fire execution of script in background via click?
within cms/crm , want trigger external file load when clicking on link within cms/crm.

e.g. activate php.mailer send email.

it seems security issue when using (cross domain vulnerability?) 

foobar.onload()

and if weren't, not execute file in background. have seen solved in python using 

subprocessor()

.

the external script on domain though , not touch cms / crm.
ideas?

in javascript can't access filesystem, can use ajax request url differents methods (get, post...).

the script called url can execute function send email if want.

if know jquery, can in javascript

$.get("myscript.php");

and in myscript.php file :

mail('you@mailhost.com', 'hello', 'cool !');

and if php script not on same domain, should check access-control-allow-origin header allow client (the browser execute ajax script) call remote php script
